Innledning
How to get a six-pack in ten minutes? How to lose ten pounds in one week? How to burn 500 calories in an hour? Training is a major focus these days.

Questions like these are normalized in our everyday lives and the big focus around exercise and appearance is getting bigger. However, do we know what is happening with our bodies and especially with our minds when we exercise?

By looking at how the human body is built and how it responds to exercise, we can find an answer to the main question. What is exercise doing to your body?

In this text, we will also do some research on the importance of recovery, if age has any effect, and how your mind responds to training.

With some background information and some additional knowledge, we can understand what exercise is doing to our bodies and if it is worth the effort.

Muscles grow when we stress the muscles out of their regular comfort. When this happens, the body works hard to maintain a stable internal environment.

This environment is called homeostasis (Jancer, 2018). Stimulation of muscle breakdown and protein synthesis begins when you start exercising with resistance.

Protein synthesis helps to rebuild muscles and the simulations are the ones that leave you with bigger and stronger muscles.

However, why do the muscles get bigger when you break them down? Exercise damages muscle tissue (Waehner, 2020), and after exercise, the muscle is torn down.

That is when the repair process begins. This process makes the muscles grow bigger and stronger.

Since exercise damages the muscles, the body is trying to repair it so next time it will be able to "protect" itself better.

What Happens to Your Body When You Start Exercising?
When you first start to work out, you might feel more energized. This is because ramping up your heart rate causes a boost in overall blood flow and oxygen to your brain. It also releases endorphins, which combat stress.

After the workout, you will begin to feel the muscle soreness. Then you know you have used your muscles in your body.

The soreness will persist for about 72 hours. If you start working out regularly, you are less likely to feel it again.

After a while, with regular exercise, you will slowly start to ramp up the production of mitochondria.

Mitochondria are a part of your cells that convert carbs, fat and protein into fuel for your muscles. With this fuel, they can do their work like contract and flex.
